STOVE.

SPECIFICATION forming part of Letters Patent No. 311,592, dated February 3, 1885.

(No model.)

a To all whom it may concern.-

heating-stoves, the object being to economize in the consumption of fuel and retain the products of combustion in the stove and its connecting parts until all of theheat has been abstracted; and it consists of certain novel features in the construction and arrangement of the different parts, as will be hereinafter more fully set forth and claimed.

Figure 1 is an elevation of a stove embodying my improved features; Fig. 2, a Vertical section; Fig. 3, a horizontal section in the plane 00 at; and Fig. 4, a horizontal section in the plane y 3 Fig. 1.

Referring to the drawings, A represents the base of the stove, A the heating-cylinder and fire-box, and A a heating-drum. The base of the stove is hollow, forming the hot-air chamber B, while the partitions a a on each side of the front part of the cylinder separate the draft'opening a from the hot-air chamber B. The lower end of the cylinder or firebox sets well down into the chamber-base, in order to keep the same in a highly-heated condi tion. The vertical hot-air or draft pipes'B B, located at the back part'or corners of the stove, communicate with the interior of the cylindrical fire-box by means of the horizontal pipes a a connecting with the fire-box near the lower end, and the companion horizontal pipes b I), connected at the top of the cylinder. The connections I) b are provided with dampers, so that the heat may be forced into the vertical pipes through the horizontal connections a a When supplying fuel to the stove, the dampers in the pipes b b should be opened, so as to provide a free escape for the gases in the upper part of the cylinder when the door b is open. The heated air will ordinarily pass from the fire-box into the pipes B B through thelower connections, the upper ends of said vertical pipes beinginserted in the under side and back part of the heating-drum A located just above the top of the stove. This drum is provided with a number of diaphragms, 0, having each alternate end cut away, so as to leave a passage between alternate ends of the diaphragms and the inclosing-walls of the drum. Theheated air escaping from the stove into the drum is thus compelled to pass up and over the first diaphragm, when it strikes and is deflected by the next diaphragm, and so on until the front side of the drum is reached, when the heated air is returned to the front of the stove by passing down through the return-pipes G and from thence discharged into the chamber B in the base of the stove, from which the unconsumed products escape to the outer atmosphere through the smoke-pipe located at the back side of the stove. This construction and arrangement provides a large amount of radiating-surface, so that the full benefit of all the fuel consumed is obtained before the products of combustion escape into the outer atmosphere. The bottom of the tire-box just below the grate D is provided with elongated openings corresponding to the openings d in the grate. Fig. 3 shows these openingsin line for the admission of air to the lire-box. Fig. 4 shows the grate moved to one side, tightly closing the openings and preventing the air from entering the lire-box, thus forming a double grate.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a heating stove, the combination, with a hollow base provided with the partitions a a, of a heating-cylinder adapted to set well down inside of said. chambered base, the ver tical smoke-pipes B B, the horizontal pipes a a the companion horizontal pipes 12 b, the heating-drum A", and the pipes O C 0 substantially as and for the purpose set forth.

2. In a heating-stove, the combination, with the heating-drum A, connected with the firepot, and provided with "a number of diaphrams having alternate ends cut away, of the pipes 0' C the chambered base A, and the pipe 0 substantially as set forth.
